FRICTION" Application fil ed June 14,

The invention relates to improvements in Z the type of friction tension wheel known in the art as a pressing roller which is used'extensively on spinning frames intextile mills,

- 'and which usually consists of a hexagonal shaft with ends and central part turned,

' "L round for bearings, and two belt-leather tired wooden wheels driven on the remaining hexagonal spaces, so that the wheels may be spaced closer or fartherapart as required by driving the wheelsin a direction along the axis of the shaft.- s I V Some of the objects of my invention are toprovide a tire of better material, WlllOll y is more readily renewable, and. which will stand 'truing up oftener because of its increased cross section, and a mechanical construction which facilitatesthe adjustment of I the wheels along the axis of'the shaftas well as allowing a ready renewal of worn parts.

A form of my invention is illustrated in the accompanying drawing wherein-5 Fig. 1 is a plan view of theassembl'ed section. e, i i Fig. 2 is an end viewv with part broken away to show the interior construction of.

Fig. 3 is a detail of the wheel hub. Y e i Similar numerals refer to similar parts thruout the several views. i

A, shaft 10 is threaded ing bearings 13, 14 and 15.

- threaded to correspond to the threads on the shaft are screwed on to the threaded parts thereof. 1

The tires 17 and 18 which may be made of molded paper, cloth or other fibrous composition held together by suitable synthetlc resin, furnishingthe desired strength and surface texture, are providedat their inner 'diameterswith semi-circular notches which engage tubular rivets 19,120'and 21 and have their sides recessed to recelvei plates such as 22 and 23. I

These plates 22 and 23r have holes, near their outer circumference for rivets 19, 20

and 21 which also correspondto'the driving riveted to each tire to form ither web of the structure with one'of the wheels shownin at 11' and 121 Hubs 16 having their inside diameter 1928:. enu ne.355,352; a V notches at the dinner, diameter the -tires and the center holes are0f-suh form as to fit over the splined hub;16.=' 1

Nuts 24, 25,etc bearing washers 26," 27,. etc, serve to securely, hold the wheel in any desired axial position onthe shaft to withinthe range of the threaded portion.

Previous to riveting the tires and side plates togethera length of tubing as at 28is' placed between the plates, This tubing, g
